Guiana Space Centre
The Guiana Space Centre or, more commonly, Centre Spatial Guyanais (CSG) is a French and European spaceport near Kourou in French Guiana. Operational since 1968, it is particularly suitable as a location for a spaceport as it fulfills the two major geographical requirements of such a site:
- it is quite close to the equator, so that the spinning earth can impart some extra velocity to the rockets for free when launched eastward, and
- it has uninhabited territory (in this case, open sea) to the east, so that lower stages of rockets and debris from launch failures cannot fall on human habitations.
The European Space Agency, the French space agency CNES, and the commercial Arianespace company conduct launches from Kourou. This is the spaceport used by the ESA to send supplies to the International Space Station using the Automated Transfer Vehicle.
The location was selected in 1964 to become the spaceport of France. When the European Space Agency (ESA) was founded in 1975, France offered to share Kourou with ESA. Commercial launches are bought also by non-European companies. ESA pays two thirds of the spaceport's annual budget and has also financed the upgrades made during the development of the Ariane launchers.
Kourou is located approximately 500 kilometres (310 mi) north of the equator, at a latitude of 5°10'. At this latitude, the Earth's rotation gives a velocity of approximately 460 metre per second (1,000 mph; 1,700 km/h) when the launch trajectory heads eastward. The proximity to the equator also makes maneuvering satellites for geosynchronous orbits simpler and less costly.
The near-equatorial launch location provides an advantage for launches to low-inclination (or geostationary) Earth orbits compared to launches from spaceports at higher latitude. For example, the eastward boost provided by the Earth's rotation is about 463 m/s (1,035 miles per hour) at the Guiana Space Centre versus about 406 m/s (908 miles per hour) at the United States east coast Cape Canaveral and Kennedy Space Center spaceports which are at 28°27′N latitude in Florida.
ELV (CECLES/ELA-1) 
Originally built in the 1960s under the name of CECLES (French: Conférence Européenne de Construction de Lanceurs et d'Engins Spatiaux, English: European conference on construction of launchers and spacecraft), the ELV pad (French: l'Ensemble de Lancement Vega) located at was designed for the Europa-II rocket. One Europa-II was launched from the site, before the programme was cancelled.
The pad was demolished, and subsequently rebuilt as the first launch complex for Ariane rockets. Renamed ELA (later redesignated ELA 1), it was used for Ariane 1 and Ariane 2 and 3 launches until being retired in 1989.

ELS / Soyuz at CSG 
ESA has built ELS (French: l'Ensemble de Lancement Soyouz) at for launching Russian-built Soyuz-2 rockets. The first Soyuz launch from ELS was postponed several times, but launched on October 21, 2011.
ELS is located on the territory of Sinnamary commune, 27 km (17 mi) from Kourou harbor. It is 10 km (6.2 mi) north of the site used for the Ariane 5 launches. Under the terms of the Russo-European joint venture, ESA will augment its own launch vehicle fleet with Soyuz rockets—using them to launch ESA or commercial payloads—and the Russians will get access to the Kourou spaceport for launching their own payloads with Soyuz rockets. Russia will use the Guiana Space Centre in addition to Baikonur Cosmodrome. The Guiana location has the significant benefit of greatly increased payload capability, owing to the near equatorial position. A Soyuz rocket with a 1.7 tonnes to geostationary transfer orbit (GTO) performance from Baikonur, will increase its payload potential to 2.8 tonnes from the Guiana launch site.
The rocket assembly procedures will differ from ones used at Baikonur. Traditionally, the Soyuz gets fully assembled in horizontal position, then transported to a launch pad and erected for launch. In ELS the rocket solely is assembled in horizontal position, then transported and erected. A spacecraft is then transported to the pad separately and attached to the rocket. To protect from dust and wind, the launch pad will have a closed gantry. The gantry will be able to move away from the pad for launch.
The ELS project is being co-funded by Arianespace, ESA, and the European Union, with CNES being the prime contractor. The project has a projected cost of approximately €320 million, where €120 million are allocated for modernizing the Soyuz vehicle. The official opening of the launch site construction occurred on 27 February 2007. Excavation work however, had previously begun several months beforehand. As of May 2008, groundworks were still continuing but the flame pit was substantially complete, along with the shell of the Soyuz assembly building. Equipment manufactured in Russia had arrived in French Guiana by July 2008, with Russian technicians performing the equipment installation at ELS.
In November 2007, reports emerged attributed to Vladimir Grezdilov, general director of the Mir company, of thefts from the Soyuz site near Sinnamari, which could cause delays to its completion and the first launches.
On May 21, 2009, Russian news agency ITAR-TASS reported that the first two Soyuz-ST to be launched at ELS have been built, tested and prepared for delivery to ELS.
On August 25, 2009, the general director of the Progress design bureau Alexander Kirilin said that the first launch of the Soyuz-ST from the Kourou space center was postponed for the beginning of April 2010. He informed that the first three rockets had been built and would be shipped on November 1, 2009 by sea.[dated info]
On September 13, 2010, Spaceflight Now reported that after several delays in the construction of a mobile gantry the launch pad had been finished, and the first flight of the Soyuz is expected to occur in early 2011. By October 2010, 18 launch contracts have been signed. Arianespace has ordered 24 launchers from Russian industry, with the first two already delivered to CSG.
On January 14, 2011, BBC reported that the Soyuz launch complex will have its qualification review in April with the expectation for the first Soyuz to lift-off sometime between 15 August and 15 September [of 2011].
On December 17, 2011, another Soyuz was launched from Kourou carrying the French space agency's Pleiades 1 A Earth imaging satellite, four ELISA electronic intelligence satellites, and the SSOT remote sensing satellite for the Chilean military.
On December 1, 2012, Pleiade 1 B, twin of the above, was put into orbit by yet another Soyuz.
Final assembly building 
Astrium assembles each Ariane 5 launcher in the Launcher Integration Building. The vehicle is then delivered to the Final Assembly Building for payload integration by Arianespace. The Final Assembly Building is located 2.8 kilometres (1.7 mi) from the ELA-3 launch zone. The mobile launch table completes the trip with an Ariane 5 in about one hour. It is then secured in place over the launch pad's flame ducts.
Launch safety 
Fire safety is ensured by a detachment of the Paris Fire Brigade. Safety around the base is ensured by French Gendarmerie forces, assisted by the 3rd Foreign Infantry Regiment of the French Foreign Legion.
Before and during launch windows, CSG facility security is significantly enhanced by anti-personnel and anti-aircraft measures, the exact configurations of which are classified by the French military. All entrants to the launch complex are also subject to checks for proof of permission to enter the facility.
The Guiana Space Centre (as per CNES) also holds the Îles du Salut, a former penal colony including the infamous Devil's Island. Now a tourist site, the islands are under the launching trajectory for geosynchronous orbit and have to be evacuated during launches.
